Ever since Firefox made Youtube videos only play in HTML5, no matter what quality setting I have on the video I'm watching, when I view the video on fullscreen it has low framerate. This problem does not happen with other video sites that uses Flash, like Twitch, Blip, or Dailymotion.

Is it software related to the browser or hardware related with it being HTML5?

I'm a web developer, and I've been working on creating a site ( http://mythicalslab.x10host.com/ ). On the site I have some javascript that handles displaying a div with a loading animation on it. In script html tags, I have two function defined, hideLoading() and showLoading() which respectively show and hide the loading animation.

If I go into the Javascript console in Firefox, and either type hideLoading() or showLoading(), the console says "undefined", but it still runs the function correctly.

If you want to check this put for yourself, go to my homepage ( http://mythicalslab.x10host.com/ ) and type showLoading() in the dev console, and you'll see it will run the function and show the loading animation, while saying it is undefined.

I'm on a Mac running Yosemite and my Firefox has been stuck at 37.0.2 for months now. It continually beeps at me saying the newest version is ready to install but when I click it and say sure--go ahead and install--it seems to go through all the motions downloading then tells me the updates will be installed when I restart Firefox, then it never updates and I'm still at 37.0.2. This has been happening for months. I've downloaded/installed/restarted Firefox and my computer a zillion times and it never takes and just keeps beeping at me to install the latest version of Firefox. Never had this problem before, the installs always worked seamlessly. Help!!

Problem grew progressively worse over 2-3 days. First, a few bookmarks disappeared from the toolbar. At the same time, "Bookmark This Page" stopped working, and the "Recently Bookmarked" list went blank. When I followed the Firefox-recommended procedure to backup and restore, I repeatedly got the message that Firefox was unable to process the restore. Then 3/4ths of my bookmark folders disappeared. This happened trying it with several different backup dates. Now I find that a number of other people are having similar problems. Like some of them, my problem may have started during a restart due to a lockup in another program. The Mozilla Support system seems way too complicated, time-consuming and circular, and talking to a live person does not appear to be an option. If this isn't fixed in the next 24 hours I'm trying other browsers, after using Firefox almost exclusively for several years.

Recently in this week, when I open up Firefox, it automatically opens up a new tab and loads Bing. It originally only loads up my previous tabs, and only activates the one I was showing last time. It still does pretty much the same thing, with the one I was reading on my last visit activated, but it then opens up Bing. I didn't pay attention to it the first time, just got suspicious since I never used Bing(kinda hate M$ to begin with) so that wouldn't be my last site visited. I did checked and it is the real Bing and not a phishing site of a virus, and simply closed the tab. I started to get annoyed by the third time, so I got into about:config and deleted all the results that returned Bing. Just two of those and none seems to matter at all to my current situation. I made sure that google is my only search provider, closed the browser and restarted it, Bing didn't pop up that time so I thought I'm fine. But the next day, same thing happened again, and don't have any results in about:config with Bing. My homepage is a blank page, and my new tab page is the Firefox default one(with google and some of the sites I pinned. I have some plug-ins and add-on installed, but none are related to Bing, and I installed all of them quite long ago, so it doesn't seem to be a recent plugin that screwed me. And no, I am not stupid enough to have Bing bar installed and not noticed it.

I did a search in my about:support page, and it returned no "Bing" results, and the "Search" results returned 2, Tineye and google scholar. The only Microsoft addons I have is sharepoint and lync.

This thread on the forum, https://support.mozilla.org/en-US/questions/1038882, seems to be the closest to my situation, but none of the anwsers helped. If I open another Firefox window, it goes to the Firefox start page.


Thank you in advance to anyone who tries to solve this problem.

After hovering on or after clicking the back (or forward) button when I move my mouse away from it Firefox automatically opens the mini history drop down menu for that tab. This happens if I don't click or after clicking once but not holding the mouse button down. I then have to click somewhere else on the page to close it. Very annoying!

It only started after I upgraded to V37 and it doesn't do it on my Windows computer which is also on V37.

This only happens if I move my mouse pointer in a downwards direction from the button. If I move my mouse up or to the side of the button before moving away it doesn't open the drop down menu. Strangely that is quite difficult to do in normal practice!

I hope somebody can help with this it is driving me mad :(

This is not so much a question, as an answer that some people desperately need.

Ever since Version 34, Firefox has done a superb job of restoring the tabs that the user has created, either on restarting Firefox (if that option is chosen) or on request.

The details of how to restore tabs are covered in Firefox's basic help online, and even how to deal with several crashes in a row (such as in an addon) ruin the normal backup file are also well explained.

However, today I accidentally pressed Alt+F4 twice on my poorly-designed keyboard and closed my main window, with 93 tabs, and another Firefox window as well. I'm not sure this is exactly what happened, but I lost all 93 of my tabs.

I read many of the postings in which people give various suggestions, but none worked. Every time I restored a version of the sessionstore.js file I saw the same lonely empty tab. Restoring prefs.js did nothing, and neither did making changes in the internal configuration constants.

I tried refreshing/resetting Firefox (which preserves bookmarks), but I still couldn't restore the tabs. It was now clear that the problem was in sessionstore.js (and all its backups) for sure.

I'm writing this for people who must restore their windows or tabs, and don't mind getting technical about it. That was my situation.

The solution was to realize that the sessionstore.js file contains JSON code, which is an efficient way to represent integers and strings arranged in a tree structure.

I figured there must be a JSON editor somewhere, and it turns out there is a great one available online, at www.jsoneditoronline.org . It can read a file on your computer, edit it, then save it back on your computer.

As soon as I viewed sessionstore.js in the editor, it was obvious how easy this was going to be. The top level of the tree is understandable. I simply grabbed the data representing the window with 93 tabs, and dragged it from the list of closed Firefox windows to the list of open windows. This automatically moved the history of each tab, and even the strings entered into forms.

After copying sessionstore.js back to the Firefox profile, I started Firefox one more time. The playing of Pandora signalled that my tabs were back and functioning once again.

Now, editing JSON code is not something that everyone is ready for. And your problem might not be reflected in the JSON tree so simply. But, for technical-minded people who don't want to lose their tabs or windows to a mistake or a crash, this technique can be just what's needed when everything else fails.

Using firefox desktop for mac. Recently it stopped saving my history. Forward and back buttons still work, typing something in the address window will make it pull up places I've visited in the past, but only ones I visited two or three weeks ago. Nothing recent. "Show all history" brings up the window, but there is nothing in it."

Private browsing is not enabled. I have enabled "remember my browsing and download history."

Another answer suggested I might have an anti virus or something that is disabling history. I looked, but I don't have anything doing that. Safari and Chrome are both saving their histories normally.

Any help would be appreciated. Thanks.

Firefox has started to display my homepage (www.msn.com) as a newsfeed rather than the full content. I tried clearing my cache and it worked once, but has gone back to displaying as a feed. If I use another browser, such as internet explorer, the page displays correctly.

The feed display is unacceptable. I don't want to use another browser, but will be forced to do so if this problem can't be corrected.
